New Tests at the Top

Dividng Plants in September
I’ve got a few plants I’m trying to divide Sept. 13th. One plant became seven. We’ll see how they do this late in the season.


Anise Hyssop – Can I cut off a piece and root it by sticking it in the ground?
Answer – Yes – but keep it well watered.

Coreopsis If I cut this to the ground, will they come back?…..Results: YES. and will FLOWER

Dames Rocket
If I pick the seed green, will it ripen and open the seed easily.
Answer – NO.
Seeds seem to ripen best on the plant. If you have to cut green seeds out – pitch them.

Gairailladia – Blanket Flower If I take seed off the plant and cover it with dirt – will it germinate immediately?
Answer – NO – all seeds have a period of dormancy.

 New England Aster
1. Cuttings taken in spring. They are starting to bloom in Mid-September
2. I also cut plants to the ground in Mid-august. They are now coming back and blooming low to the ground.

Is it better to just dead-head it or cut it back to the ground?
Answer –  cut it back to theground. Note – this is also true of veronica

Aug 25 – took out zinnias in front and transplanted in VB, tropical milkweed, buddleia, blazing star, purple french hollyhock, milkweed cuttings. Also transplanted four echinacea from test bed – these are seeds I planted last fall.

Verbena vonareinsis – C
Malva purple – B
Tropical Milkweed – A
Gaillardia- blanket flower – B
Meadow BS – C
Buterfly Bush – C – need to cut quite a bit off.

Zinnia Seeds
Will Zinnia Seeds from this years plants germinate?
Results: Yes! I saved some seeds from this years crop – usually it takes months for these seeds to be ready to plant, but these germinated easily.

    I just bought some root cuttings of ASCLEPIAS SYRIACA from a garden centre which way up do you plant them and is it best to grow this in a big pot to stop it spreading Thanks, June.

    • I’ve never grown Ascelpias syriaca from roots, but I’d guess that you lay them in horizontally. That’s the way the roots run in the garden. Cover them up about a half inch and hopefully they will sprout.

      I did grow this variety in a large pot and it came back this year. I left it outside and it did well.

      I’ve grown this in the garden and it took over, so I had to get rid of it.

      Have you ever seen a Monarch butterfly in the UK?
